Question

Or a list of registered parts ?

tried

[Import]
CompositionContainer container;

but it failed

Answer 1

Make sure that your Bootstrapper is exporting the CompositionContainer.

Starting with Prism’s ModularityWithMef sample, I added the following to QuickStartBootstrapper : MefBootstrapper

    protected override void ConfigureContainer()
    {
        base.ConfigureContainer();

        this.Container.ComposeExportedValue<CompositionContainer>(this.Container);
    }

Then I was able to access the CompositionContainer from other modules.

Also try using [Import(AllowDefault = true, AllowRecomposition = true)] to get out of dependencies.
